Ear ringing may be caused by cerumen, otitis media, Meniere’s disease, tympanitis and so on. 1. Cerumen: Cerumen has a protective effect on the external auditory canal and tympanic membrane. When the local area is irritated, it causes excessive secretion of cerumen and obstruction of cerumen discharge, which leads to ringing in the ears, accompanied by earache, hearing loss, tinnitus and other symptoms. 2. Otitis media: This disease is mainly caused by viral or bacterial infections. When it occurs in upper respiratory tract infections, viruses and bacteria will enter the middle ear through the Eustachian tube, which will result in abnormal ringing in the ears, accompanied by congestion and swelling of the Eustachian tube. 3. Ménière’s disease: the pathology of this disease is characterized by the expansion of the membranous labyrinth, which may be related to the imbalance of lymphatic production and absorption, resulting in abnormal ringing in the ears, accompanied by hearing loss, vertigo, a feeling of fullness in the ears, tinnitus and other symptoms. 4. Tympanitis: Ear ringing may be caused by tympanitis, usually associated with infection, drugs, physical stimulation and foreign bodies in the external auditory canal, etc., the main clinical manifestations of ear pain, tinnitus, ear overflow, hearing loss and other symptoms. It is recommended to go to the regular hospital in time, under the guidance of the doctor, according to the specific results of the examination, to take targeted treatment.
